One way to show digital pictures and video to friends and family is for all to circle around the home computer screen. Alternatively, you can connect your tv to your computer and send the images to the TV. Technology also exists to network a TV and a computer in the other direction, so that you can watch television programs on your laptop or PC.
Showcasing digital images on the television
With a digital camera or video recorder, user can create multimedia image files stored on their PCs. Showing these images to others can be inconvenient, however, especially if your computer screen is small and located in a private room of the house. Displaying them on television usually allows you to show them at a larger size and in a more comfortable location.
You can connect a computer to a TV either wirelessly or with cables. The method you choose depends on the types of connections your TV supports as well as your budget for purchasing additional hardware.

Viewing television on the PC
You may also be interested in watching television programs on a computer. This is also possible with the right wired or wireless equipment installed. Some TV broadcasts are accessible directly via the Internet and no connection to television is required. Those who own Digital Video Recorders (DVR) may also prefer to connect their computer to the DVR rather than the television directly.
Connecting Computers to TVs through Wires
Televisions do not normally support Ethernet cable connections. Instead, you will typically connect your laptop or desktop PC to a TV using one of the following types of audio-visual (AV) cables:
· DVI or HDMI-to-DVI
· Any of the above – to-SCART (in Europe)
A scan converter converts the computer’s video signal into standard TV formats. You may need to set up a scan converter to connect your computer and TV if, between them, the two do not support any compatible combination of AV cable technologies listed above. Latest televisions, however, generally support multiple types of digital inputs and finding the right cable should not be too difficult.
•Connecting Computers to TVs Wirelessly
In place of using cables, you can also use Wi-Fi to connect computers and TVs wirelessly. Since televisions do not ordinarily support Wi-Fi, you will need to install a separate unit between the computer and TV. One common solution is called a Wireless PC to TV system or [i[Digital Media Receiver. These products connect via AV cable to the TV and supply Wi-Fi connections to any computer in the home.

Another wireless PC to TV connectivity option is based on Windows Media Center Edition (MCE). If you purchase a Windows XP or Windows Vista PC with the MCE application included, this system contains built-in wireless connectivity support for streaming images to your television. A few of these systems also support TV tuner cards that allow your computer to receive incoming television signals. Finally, you can extend the capability of a Media Center PC across an entire wireless home network by installing a Media Center Extender product like the Linksys DMA2100.
